It is a 90 degree right angle that has its own special symbol which looks like a small square in the corner.

It is called a Reflex angle. These are angles greater than 180 & less than 360. i hope that helps
asuming you know how to construct a 60 degree angle, you would start by drawling a basic construction line an then make your angle bisecter with breaks the angle into 30 degree angles. then create another angle bisector for 30 degrees breaking it into 15 degree angles. then do the same with the 15 degree angle. your drawling sould have three angle bisectors for each angle. to get your answer of 22.5 degress angle, simply add the 15 degree angle you drew with the 7.5 angle you got from spliting the 15 degree angle in half its hard to explain without drawing it out..... hope this helps
acute=less than 90º right angle=exactly 90º obtuse angle=more than 90º but less than 180º straight angle=180º re''flex angle= An angle greater than 180° and less than 360° An example well let 's see : a lamp , a cup , a small rubber ball , an electronic vacuum , cream top , glasses and any thing circular demonstrates an example of a right angle , obtuse , straight , full rotation circle , reflex ,acute & zero angle & a zero , O , & orange ....hope that helps !!:)
There are 2 angles in a Rhombus. An acute angle and an obtuse angle. Hope this helps and if it doesnt then please write on my comment board and i will give you some more information about it as soon as possible. Thankss
It depends on what you mean. If you are looking for ONLY one right angle, then the only "named" quadrilateral I can think of is a kite. If you are looking for a quadrilateral with AT LEAST one right angle, then there are squares, rectangles, trapezoids, and kites. Of course, there are quadrilaterals out there without specific names with only one right angle or at least one. Hope this helps you! :-)
